WEATH ER-STRI P.-

SPECIFICATION forming part of Letters Patent Nb. 616,695, dated December 27, 1898. Application filed October 26, 1896. Serial No. 610,095, (No model.)

IO pecially to that class known in the art as metallic weather-strips, formed of a cushioned portion inserted and clenched in a metallicbacking or frame, by which the entire article may be secured in the desired position. The main idea of manufacturers of this class of articles is to produce an efficient strip with the least amount of material. In other words, simplicity istheir object. This can readily be appreciated from the fact that 20 many thousands of feet of this article are manufactured annually, and a weather-strip that will save from twenty to twenty-five per cent. means a large amount in the aggregate.

The object of my invention is to provide a 25 simple, economical, and eflicient weatherstrip of the metallic type; and the invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an enlarged perspective view of a weatherstrip made in accordance with my improvement; and Fig. 2, a transverse sectional View of the same, taken on line 2 of Fig. 1.

In the art to which this invention relates the most usual method of constructing this particular type of strip is to fold the rubber portion so that the edges are approximately parallel and then crimp it in the metallic The most serious objection to this method is that one or both edges of the cushion portion are apt to be pulled out of the frame portion during the manipulation incident to securing it in position for use.

Various methods have been designed for overcoming this objection; but they are all objectionable, in that they require the use of more material and largely increase the weight as Well as the cost of manufacture. The principal object of my invention, therefore, is to avoid all of these objections and provide a weather-strip that will practically be no heavier than the common strip and as economical to manufacture.

In constructing a weather-strip in accordance with my improvements I make a cushion portion A of the desired material, shape, and size and fold it longitudinally, so that its lateral edges a are brought into substantially the same vertical plane. I then secure such edges together by what I term overstitching B, which also forms a lateral projection over and around the edge. I then insert the cushion in the metal frame 0, which is folded .over at c to grasp the lateral projecting edge and firmly hold the same in position.

The advantages of my strip are apparent to those familiar with the art; and it consists principally in the economy of manufacture, the small amount of material used, and the peculiar method of stitching the edge of the cushion portion together, which also acts as a locking edge.

I claim- A weather-strip consisting of a cushion portion of rubber or similar material folded longitudinally with its edges secured together by chain and over stitching so as to securely hold it and act as a projecting locking edge, and a metallic frame portion having one of its lateral edges folded over so as to embrace the overstitched locking edge of the cushion, substantially as described.
